MIAMI -

Former Florida Gov. Charlie Crist is running again -- this time as a Democrat -- according to the Florida Department of Elections' website.

Crist is expected to make the announcement official on Monday in St. Petersburg.

Crist, then a Republican, served as governor from 2007 to 2011. He made a failed bid for Senate as an independent, then switched parties.

Crist is expected to run against current Governor Rick Scott, who hasn't filed his paperwork, according to the website.

Republican Party of Florida Chairman Lenny Curry issued a statement Friday, saying: “Charlie Crist has now officially filed to run for the position he once abandoned. When Florida needed Charlie Crist the most during difficult economic times, he ran away. If he really wants to be Governor now, why did he quit the first time?”
